Cox, signed to a four-year, $20 million contract as an unrestricted free agent
last March, was a disappointment in his lone season in San Diego. The former
Jacksonville Jaguar lost his starting job in midseason and managed just 38
tackles and one interception in 16 regular-season games.

The five-year pro's $4.25 million base salary for 2014 would have been fully
guaranteed if he remained on the roster by March 13.

McClain was entering the final season of a three-year deal he signed with San
Diego in 2012 and saw a limited offensive role this past year, recording 32
yards on 11 carries and a pair of receptions.

Patrick registered 38 tackles, one interception and 1 1/2 sacks in 13 games (4
starts) last season prior to landing on injured reserve with an ankle issue.
The 25-year-old was claimed off waivers by San Diego from the New Orleans
Saints last February.
